Speed and Parking fine from France - Aug 2018

[wel7on]

Hello,

I've just had a speeding fine through the post, relating to August 2018. From speaking to the hire car company it looks like we have picked up 1 x speeding fine and 1 x parking fine.
The parking fine has not come in the post (yet)

Just to be clear I have no issue with paying the fines as we must have been speeding.
We genuinely do not know who was driving at the time as we shared the driving, its fairly safe to assume it was me rather than my wife 😁

However, the timescale seems a bit long. Can they really send it 6 months later and then enforce payment? And is it just the speeding fines they can send or will the parking come separately?

Thanks for any advice / thoughts
